Setup
Proper setup is crucial for the safe and effective operation of your inverter.
Connecting to a 12V DC Power Source:
- Ensure the inverter's power switch is in the 'OFF' position.
- Identify the positive (+) and negative (-) terminals on your 12V battery and on the inverter.
- Connect the red (positive) battery cable to the positive (+) terminal of the battery and the positive (+) terminal of the inverter.
- Connect the black (negative) battery cable to the negative (-) terminal of the battery and the negative (-) terminal of the inverter.
- Ensure all connections are tight and secure to prevent arcing or overheating.

Mounting (Optional):
The inverter can be permanently mounted using the integrated brackets. Choose a dry, well-ventilated location away from direct sunlight, heat sources, and flammable materials. Ensure sufficient space for airflow around the cooling fan.
Operating Instructions
Once properly connected, follow these steps to operate your inverter:
- After securing all DC connections, switch the inverter to the 'ON' position. The power indicator light should illuminate.
- Plug your AC appliances into the NEMA-20R GFCI duplex outlet on the front panel.
- For USB charging, connect your devices to the available USB ports.
- Monitor the inverter's status indicators for any alarms (e.g., low battery, overload).
- When finished, switch the inverter to the 'OFF' position before disconnecting any appliances or the DC power source.

Maintenance
To ensure the longevity and optimal performance of your Samlex PST-2000-12 inverter, perform the following maintenance tasks:
- Regularly inspect all cables and connections for wear, corrosion, or damage. Tighten any loose connections.
- Keep the inverter clean and free from dust and debris. Use a dry cloth for cleaning.
- Ensure the cooling fan vents are unobstructed to allow for proper airflow.
- Store the inverter in a cool, dry place when not in use for extended periods.
Troubleshooting
If you encounter issues with your inverter, refer to the following common troubleshooting steps:
- No Power Output: Check battery connections, ensure the inverter is switched ON, and verify the battery voltage is within the operating range (10.7 - 16.5 VDC).
- Low Battery Alarm: Recharge your 12V battery. The inverter will shut down automatically to protect the battery from deep discharge.
- Overload Protection: If the inverter shuts down due to overload, reduce the connected load. The inverter will automatically reset once the overload is removed.
- Overheating: Ensure the cooling fan vents are clear and the inverter is in a well-ventilated area. Reduce the load if necessary.
